The Atmos is hidden inside the EAC3 audio track it self, if the movie do contain Atmos.
To my knowledge then Atmos is only being used on 4K video on the streaming services, so that limits it for StreamFab to only HBO Max.

Nope, I believe that is incorrect. I've seen numerous releases of titles online from Netflix, Amazon, etc that include Atmos as a separate type of DDP 5.1. Regular DDP 5.1 is listed in Mediainfo as "Enhanced AC-3, Dolby Digital plus" and the max audio quality is 640kb/s, whereas the kind of track that also contains Atmos is called "Enhanced AC-3 with Join Object Coding, Dolby Digital Plus with Dolby Atmos" and the max audio quality is 768kb/s . Also I know for certain that this specific audio track doesn't require L1 or a special type of DRM, just plain L3, as I have another program (that works differently than Streamfab but it shouldn't matter in this case) that can recognize the DDP 5.1 with Atmos track just fine, and I'm quite sure that program doesn't have any special tricks to access that track. So, my point is, I believe it's very possible (correct me if I'm wrong) to update the modules (at least Netflix and Amazon) to support Atmos with DDP 5.1 audio track, and have the "Atmos" bit show in the audio track selector in case people don't want Atmos in their copies.
